To all whom t may concern:

Beit known that I, CHARLES B. REYNOLDS,

i a citizen of the United States, residing at, v Sawtelle, in the county of Los Angeles and -State of California, have lnvented certain new and useful Improvements in Airless Tire-Cores; and I do hereby declare the f ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled -in' the art to which it apper- `tains Vto make and. use the same.

'woven linen and woolen fabric cemented together inthe formation 'of'a tire ornshoe, having a vegetable wax tread embedded therein to provide resiliency to the shoe or l tire.

Anotherr object of' this invention is to provide the filler constructed from compositions of materials bound together by tape and 'fabric belting in circular formation, be-

ing protected by a steel protector to pro- 'i will 'become more apparent as the description proceeds, the invention consists in certain novel features of constructlon, com blnation and arrangement of parts as will be hereinafter more fully described and claimed. l

For a complete understanding of my in vention, reference is to be had to the following description 'and accompanying drawing, in which f Figurel is a transverse sectional view of an airless tire core, constructed in accordance with my invention, and

' y `tional view of the same.

Referring in detail to the drawing, the numeral 1 indicates a tire or shoe, constructed of a plurality of layers of woven linen and woolen fabric, 2 and 3, cemented or otherwise secured together, which are so arranged to form beads whereby the tire or "shoe may be clamped toA the rim of a wheel. A vegetable wax trea 5 is embedded in the 'shoe-or tire 1 between,4 he layers of linen and cause pneumatic tm s,

The filler w nich is positioned within the i tire or shoe 1 above described, consists -of comminutcd cirk .mixed with cement and compressed in layers 7 and 8 around 'a' core orl filler which is later removed. The layers of comminute cork are Wrapped with tape 9 in spiral formation, which is in turn wrapped with fabric belting 1() in spiral formation and wound in the opposite rdirectionjfrom the tape 9. The tape and fabric belting entirely covers Vand, protects the layers of comminuted cork and holds themin proper formation. The filler or core whichl sponge rubber core 11, which supports the` i layers of cork and'keeps them from collapsingl, and which will render resiliencyV to the cor r.

The process of forming the, airless core afore described is as follows: The layers of cork are first made in single lengths and placed or molded about a mandrel or filler in cylindrical formation, and the. mandrel or iller is ther removedfromone end thereof and the sp1 Inge rubber coreformed in a. single length ls inserted in the space provided by the mandrel or filler. The tape and fabric belt ing is then wound on the cork in the afore described manner and the airless core is then placed within a, shoe 'or tire with the ends thereof abuttin each other.

A steel protector 12 consistlng of a steel ribbon is sp1r:.lly wound about the spirally wrapped fabrc belting 10 to lprevent the when theller is placed therein.

Fromthe foregoing description taken in connection with the accompanying drawing, it will be note :l that acushon tire has been provided which may be readily applied to the wheels of in automobile now in use and will have all of the resiliency from (pneumat ic tires, obviatlng by punctures and 'blow now obtained t e expense ts or' the` 'While I have shown and described ther preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed. 'i

Having thus described my invention, what I claim is In a device of. the che racter set forth comprising a filler consisting of layers of comminuted cork cemented together, a. core Within the layers of cork, tape spiral-1y wound' around the outer `surface of thelayers of cork, fabric belting spirally wound around 15 the tape in an opposite direction, a metallic ribbon spirally wound around the fabric beltingg,4 and a shoe surrounding the filler.

In testimony whereof I aix my signature in presenceof two Witnesses.

CHARLES B. REYNOLDS.
